PLATING-MACHINE Specification of Letters Patent.

Application filed October 22, 1907. Serial No. 398,594.

To all whom it may concern:

Be it known that I, CHARLES GLovEn, a citizen of the United States,residing at New Britain, county of Hartford, State of Connecticut, haveinvented certain new and useful Improvements in Plating-Machines, ofwhich the following is a full, clear, and exact description.

My invention relates to improvements in plating machines.

.The objects of my invention are-to provide an improved construction forplating machines, including improvements in a carrier adapted to movecertain conveyors through the plating solution, which conveyers may bereadily detached at will for the substitution of new articles to beplated.

The particular advantages will be appreciated by a reading of thefollowing descriptron.

In the drawings Figure 1 is a view in end elevation of the machine withthe tank in section; Fig. 2 is a view in side elevation with the tankand bearings in section; Fig. 3 is a plan view of the plating machine;Fig. 4 is an enlarged detail view partly in section, and partly brokenaway; Fig. 5 is a transverse sectional view of Fig. 4; Figs. 6 and 7 areenlarged detail views of the opposite sides of one end of the conveyorframe.

1 is a tank adapted to contain the plating solution.

2 is a shaft mounted to rotate in the bearings 3, secured in the ends ofthe tank.

4 is a stuffing-box through which an extension of the shaft 2 passes. 5is a pulleywheel secured to the said extension on the exterior of thetank.

66 are the ends of the carrier frame, the same being secured to theshaft 2.

7 is a container for articles to be plated. 8 is a supporting rodtherefor. This rod may carry the articles directly or indirectly, aswhere the container 7 is used. In the latter case, the rod 8 passesthrough the con tainer at the centers of the ends 99. One or both of theends 9 may be removable, or one may be fixed in the end of the container7 and secured to the rod 8 as by key 8*, or if both ends are removablethe container may be fastened to the rod 18 by a removable pinconnection 7 and the key 8 (Fig. 4.)

10-10 are clips or buttons on the carrier frame 66 adapted to detachablyengage the rod 8 and secure the same to the respective frames. 1

11 is a handle projecting from each end 9 of the container 7.

12 is a rheostat connected to the positive terminal of the source ofelectricity.

13 is an insulated connection between the rheostat 12 and a contact 15on the bear ing 3.

14 is a reduced extension of the shaft 2. This extension 14 is mountedin the bearing 3 and makes electrical connection with the contact 15.

The carrier frame 6 may be formed in two sections. 1616 indicate aseries of arms, radiating from and in contact with extension 14, on onesection of 6, said arms being adapted to form a contact with the rods 8when the same are secured in place. 16 is a ring secured in the oppositesection of 6 and bears against the arms 1616, when the two sections aresecured together.

17 indicates a series of metallic strips or rods, rotatably secured atone end to the rods 8.

1818 are sleeve-like spacers placed between the members 17 on rod 8.

19-19 indicate negative poles suspended in the plating solution andconnected to gether in any well-known manner.

20 is a connection leading from the poles 19 to the negative pole of thesource of electricity.

The main body of the shaft 2 is preferably made of wood, or somenon-conducting material, and the same is true of the frame ends 6-6 Theshaft extension passing through the stuffing-box 4 and the extension 14are preferably made of metal, and are electrically disconnected at alltimes. It follows, therefore, that electricity entering through thewiring 13 can proceed. onwardly only by passing through the extension 11, arm 16, rods 8, the articles carried thereby, and thence through thesolution to the negative terminals 19. leakage of electricity isafforded.

The cylindrical parts of the container 7 are preferably formed ofcelluloid, or some other efficient non-conducting material of sufficientstrength for practical use in this construction, and preferably attachedto one of the ends 9 which is secured against rotation.

The operation is as follows: The proper plating solution and anodeterminals 19 are employed and put in place. The articles to be platedare then electrically connected with the rod 8. In case small articlesare to be By this arrangement no chance of plated, Which cannot beconveniently secured to the rods 8, they are placed in the perforatedbarrels 77 and are kept in circuit through the medium of the rods 17,the rods and small articles assuming the same position in the barrel bygravity. Other articles Which, for example, are perforated, may beplaced directly upon the rods 8, for instance, such as shown in thelower part of Fig. 2. These rods are detachably secured to the rotatingframe through the medium of the clips or buttons 10 on the ends 6-6 Theplating of the articles, hatever they may be, occurs in the usual mannerand requires no. detailed description. The carrier frame Within thesolution rotates at comparatively sloW speed, for example, five or sixrevolutions per minute, although the speed is immaterial. When rotatingat a comparatively sloW speed, the operator in charge of the platingmachine may easily and quickly remove any one of the rods 8 and thedevices carried thereby and substitute another one. For convenience inremoving the barrels, handles 11 are employed, al

though of course their presence is not absolutely essential.

The plating solution is preferably of such a depth as to always coverthe articles to be plated When they are in proper position to receivethe same.
